Expression

Organism Comment Expression
Synechocystis sp. construction of a DELTAPsbO/DELTASlr0228 double mutant strain that shows the presence of newly synthesized, unassembled D1 protein, especially its non-mature forms pD1 and iD1, not observed in the not in the DELTAPsbO single mutant. Inactivation of the slr0228 gene in the DELTAPsbV strain markedly increases the accumulation the monomeric PSII core complex RCC(1) and RC47 complex, the core complex lacking the inner antenna CP43, but still there is no accumulation of the dimeric PSII core complex RCC(2) additional information

General Information

General Information Comment Organism
physiological function the FtsH2 protease plays a key role in the degradation of both precursor and mature forms of D1 following donor-side photoinhibition, and in the selective degradation of photodamaged D1 protein and incompletely processed forms of the D1 protein during the repair of photosystem II in the cyanobacterium, overview. The FtsH2 protease participates in fast D1 replacement in the psbO deletion strain Synechocystis sp.
